Properties of Powders

Antimicrobial Powder Coatings
Substrate Preparation

For maximum adhesion the substrate must be thoroughly cleaned of grease, rust etc. by shot blasting, solvent or chemical degreasing. For maximum protection it is essential to pretreat the substrate prior to the application of Thermaset Limited ThermaShield Anti-microbial Polyester Powder Coating.

Aluminium

Aluminium components should receive a full multi-stage chromate conversion coating or similar chrome-free pretreatment to clean and prepare the substrate. Detailed advice should be sought from the pretreatment supplier.

Galvanized steel

Galvanized steel requires multi-stage pretreatment with either zinc phosphate or chromate conversion.

Depending on the type of galvanizing, degassing or use of anti-bubbling additives may be required. Detailed advice should be sought from the pretreatment supplier.

Ferrous substrates

Ferrous substrates require iron or zinc phosphate pretreatment. Detailed advice should be sought from the pretreatment supplier.

Application

Thermaset Limited ThermaShield Anti-microbial Polyester Powder Coatings can be applied by manual or automatic electrostatic spray equipment, an even dry film thickness of 60-70 microns is recommended. Only one batch and one spray run should be used for components that will be visible simultaneously after assembly.

Chemical Resistance

Generally good resistance to acids, alkalis and oil at normal temperatures.

Exterior Durability

After 12 months exposure, minimal loss of gloss or colour change. No film breakdown or loss of protection.
